Description

Description: TECHNICAL FIELD The present invention relates to a method for producing a multicolor solid powder cosmetic such as a foundation or an eye shadow having a marble pattern in which a plurality of colors are mixed nonuniformly.

[Conventional technology]

Conventionally, for example, as a method of filling powder cosmetics such as white powder and foundation in a gold plate of a compact case, a powdered cosmetic base made into a slurry using a solvent is poured into the gold plate from above. A method of solidifying a solvent by volatilizing a solvent is known.

[Problems to be solved by the invention]

And Thus, because the prior art methods is the vertical filling method Komu flow slurry product from above gold dish, a plurality of colors slurry of in a metal pan as shown in FIG. 4 a _1, a As a result of color separation of the slurry-like substances a ₁ and a ₂ of each color when ₂ is filled, it is difficult to produce a multicolor solid powder cosmetic having a desired marble pattern. It was

Therefore, in order to form a marble pattern in the gold plate by using the vertical filling method, the filling nozzle or the gold plate is laterally moved intricately while the slurry-like materials a ₁ and a ₂ of a plurality of colors are formed.
It is conceivable to fill them at the same time, but there is a drawback that the production efficiency is poor.

The present invention has been made in view of the above-mentioned drawbacks of the prior art, and it is possible to easily form a marble pattern in which a plurality of colors are mixed non-uniformly without laterally moving a filling nozzle or a gold plate. The present invention provides a method for producing a color solid powder cosmetic.

[Means for solving problems]

The method of the present invention, which is configured to solve the above-mentioned problems, includes a molding frame in which at least one side is open and a filling port is formed in a frame wall whose inside is a cosmetic molding part, and a powder cosmetic. Using a slurry of multiple colors produced by adding a solvent to a base, and after closing the opening of the molding frame with a permeable membrane material in a state of horizontally placing the molding frame, the slurry of multiple colors At the same time from the lateral direction into the cosmetic molding portion through the filling port of the molding frame, the solvent in the slurry of each color is sucked to the outside from the opening of the molding frame through the permeable membrane material. The multicolor powder cosmetic is solidified in the cosmetic molding part of the molding frame.

[Action]

By simultaneously pouring the slurry-like materials of a plurality of colors from the lateral direction into the cosmetic molding part of the molding frame arranged horizontally, the cosmetic molding part is filled with the slurry-like materials of the respective colors in a mixed state. .

Then, by sucking the solvent in the slurry of each color from the opening of the molding frame to the outside, a multicolor solid powder cosmetic in which a plurality of colors are shown in a marble pattern in the cosmetic molding part of the molding frame is obtained. Molded.
